About multisession configuration
Several characteristics must be considered when you configure an iSCSI multisession.
The following points apply to multisession configuration:
- The AIX® iSCSI initiator does not support multisession.
- The use of the supported iSCSI multipathing is recommended when running the I/O with multisession.
- If you use CHAP authentication under the Microsoft Windows operating system, use the same secret across each session that is initiated from that host to a particular target.
- If the Microsoft Windows clustered system is rebuilt or restored from a backup, hosts must log off and then log back on to any previously connected iSCSI targets that are supplied from the system.
- If the host application uses SCSI 3 Persistent Reservation, you must run only a single iSCSI session.
- Running with multiple iSCSI sessions is not supported for applications using Microsoft 2008 Failover clustering over an iSCSI interface; you must run only a single session in these situations.
